Hi Adi,
Both the rat skull and the nugget are small wave boards.
The nugget is slightly more performance focussed with a more refined outline and pulled in round tail. If you were after a board to surf small waves with a performance approach the nugget is the board for you.
If you were looking for a board that will provide you with heaps of paddle power and stability the rat skull is a great choice.
If you need size recommendations please email todd@boardcave.com.au

Hi, Can you please advise what the cross over between the nugget and the shortcut is. so when the nugget tops out and the smallest the shortcut works in if i was to use either as a daily driver type board.

Hi Chris, The nugget is super versatile and can be surfed in waves 1-7 ft. This is due to the extra width up the front of the board which allows for easy paddling and helps to get into waves earlier. The pin tail on the nugget holds really well in the barrel. You could use the nugget as a 1 board quiver. The shortcut is a great board for 2-5 ft if you want to ride something with a little more volume than your super high performance shortboard. It's a little thicker and wider than most performance shortboards but will still allow you to drawn tight turns and progress your surfing.
